nitrogen in air cannot be absorbed into the human body...78% of air is nitrogen that is taken in with each inhalation, and the same % leaves the body when the air is exhaled. The main source of nitrogen in the human body is from proteins. However, I have not yet heard of any function of nitrogen in the human body.

protiens...since they have nitrogenous bases attached to the amino acids (that make up the proteins)

Proteins.
Proteins break down into amino acids.
Amino acids contain an amine group (-NH2) and a carboxylic acids group (-CO2H).
